I live near City North and have been to Blue a few times now. I will definitely say that happy hour is the better time to go. The crowd is more diverse and more of the professionals relaxing after work. The food is pretty good and their signature "Blue" Martini is fun. Fridays and Saturdays are a little different. Crowded with rhinestone-clad cougars on the prowl and over-cologned men in matching striped button up shirts. If you have not gone, it is worth a stop just to people watch.
